Modular structure for versatile options
The proportional valves in sandwich design – which we have especially developed for mobile applications – control the volumetric flow internal to the actua-tor. Up-streamed individual pressure compensators (load-sensing principle) ensure the independence of the load. The flexible designed modular system is con-sisting of one inlet module, actuator modules (up to 8 sections) and one end module. As highlights, we would point out the sections with integrated onboard electro-nic and fieldbus operation. Together with our new model kit LVS18 you will alter-natively find our design with down-streamed pressure compensator and flow divider principle.Especially for the ATEX sector, there are deliverable ex-plosion proof components (device classes M2, G and D) - see also SC18Ex-Flyer 301-P-900003.
Proportional directional valve system SC18 301-FL-900002
Advantages
� High power spectrum
� Individual adaptation to the application (up to 8 actuator sections)
� ATEX certificated valves: intrinsically safe design for mining applications (device class M2) and Ex-proofed design for the device classes G and D
� OBE with CAN Open actuation, position control, characte-ristic curves adaptation and diagnostic ability. Functional safety according to EN ISO 13849, PL „c“
� Different kinds of operation: electrical, hydraulic, manual and their combinations
� Individual load pressure cut-off
� Sensitive and load-independent control – also at parallel operation
